Title: Combustion chamber for a gas turbine engine
IPC: F23R3/06
Filed: 1979-10-19
Abstract: A combustion chamber for a gas turbine engine comprises a heat- resistant ceramic flame tube (2) arranged within a cylindrical outer casing (1) with an annular space (7) therebetween. Combustion and mixing air is supplied to the flame tube (2) via the space (7) and holes (8, 9, 10, 11) in the flame tube arranged such that during combustion the flame front will expand continuously over and along the flame tube with increasing fuel flow. Preferably, the holes are arranged in axially-spaced circumferential rows, the holes in each circumferential row being arranged in diametrically-opposed pairs. The outer casing (1) may also be formed from heat-resistant ceramic material. <IMAGE>

Title: Improvements in or relating to methods and machines for applying and sealing diaphragm closures to the mouths of containers
IPC: B65B7/28
Filed: 1980-03-14
Abstract: A multi-head rotary machine for applying and sealing diaphragm closures to the mouths of bottles and other containers comprises a rotatable turret 1 carrying a plurality of sealing head assemblies. Each assembly includes a reciprocable sealing head 3, a pedestal 6 for lifting a container 7 into cooperation with the associated head 3 and operated by a conventional circular cam rail, a centralizing aperture 11 in register with the head, and a transfer device 12 reciprocable between a loading position in which a closure is loaded into the device and a sealing position. As the turret rotates, a container 7 loaded onto a pedestal 6 is first lifted into cooperation with the centralizing aperture 11, whereupon the transfer device loaded with a closure is moved to position the closure between the head and the container mouth. Thereafter, the container is lifted a further amount to contact its mouth with the closure, the sealing head presses the closure against the mouth to seal the closure thereto, the container is partially lowered with the closure sealed thereto and the transfer device is returned to its loading position, the container is again raised to cool the closure against the underside of the transfer device, and then the sealed container is lowered for discharge from the pedestal. When the diaphragm closure has a tear rab, the method of operation provides for flattening of the tab over the upper surface of the applied closure. <IMAGE>

Title: Process for Obtaining Improved Yields from Plants
IPC: A01N3/00
Filed: 1980-10-06
Abstract: A coating agent such as di-I-p- menthene and/or its polymers, optionally together with a desiccant such as diquat, is applied to plants not more than 15 days before harvest to prevent the pods or other seed- bearing bodies from splitting or the seeds from otherwise becoming prematurely detached. A surfactant may be applied at the same time. A number of other coating agents can be used. The method is used particularly with plants such as peas, beans and oil seed rape. A similar coating method can be used to prevent growth of fungi and microorganisms, and to prevent premature sprouting of the plant.
Patent GB-2068113-A (GB)
Title: Detection of faults in fabrics
IPC: G01N21/898
Filed: 1981-01-02
Abstract: Faults can be detected in a fabric, such as a tufted fabric, by scanning an illuminated surface of the fabric with a light sensitive device (4) which produces a train of electrical pulses corresponding for example to backstitches (7) projecting at the scanned surface. The pulses are monitored for irregularities and, for example, an alarm signal is produced in response to the detection of a missing pulse corresponding to a missing backstitch. In order to avoid production of false fault signals caused by variations in the background level of illumination, appropriate compensatory measures are taken during monitoring of the pulses. For example, filter circuitry may be used, or, alternatively, the pulses may be compared with slightly delayed versions thereof to facilitate accurate identification of the occurrence of a pulse. <IMAGE>

Patent GB-2116000-A (GB)
Title: Guidance system
Inventor: BROWN GEORGE
IPC: G01S11/12
Filed: 1982-03-02
Abstract: A guidance system enables a moving body (1) to be guided to a predetermined location by allowing the body (1) to view its surroundings and to compare the viewed scene (8) with a reference pattern (e.g. 24) stored on the body. A number of individual reference patterns (24, 25, 26, 27, 28, 40 etc) are stored, and each reference pattern corresponds to an area of the surroundings (e.g. 24) which is very much smaller than the field of view (8) and thus the body identifies its position by correlating its field of view (8) with one of the reference patterns (e.g. 24). To enable the body (1) to identify its position (30) even if it deviates from an expected path (31), a number of reference patterns (e.g. 24, 25, 27, 28) are laterally displaced from the expected path (31). The extent of the lateral displacements reduces with decreasing distance from a predetermined location (40) to which the body (1) is to be guided. <IMAGE>
